What I love about Macron is his unashamed centerist approach. It's new in France and I hope he has ushered in a new dimension to French politics that sticks and makes it more normal for people to vote for different parties each time based on what a manifesto actually says and who's running for elected office.
Macron reminds me a little of 1997 in the UK and Tony Blair. Let's hope he avoids turning in to a war criminal in a few years time... :)
The thing is, those left leaning student bodies are the only ones to have credible presence in most universities due to the amount of support they garner to push their communications and frankly the incompetence of the right leaning student orgs.
It's a bit of a self perpetuating cycle where the right leaning folks don't have as much support structure to coordinate because of how everyone (themselves included) see the right.
I can't speak for all ages, but the youth are incredibly passionate about politics and many hold strong anti capitalism beliefs and will enthusiastically riot at the chance to have their opinions heard.
